IMPROVEMENT IN MASH-MACHINES.

Specification forming part of Letters Patent No. 155,980, dated October 13, 1874 application tiled d September 5, 1874.

To all whom t may concern:

Be it known that we, HENRY F. SGEIMPER and J oHN H. IMMEN, both of Newark, in the county of Essex and State of New Jersey, have invented an Improvement in Mash-Machines, of Which the following is a specification:

This invention relates to that class of mash apparatus in which the mash is agitated by inea-ns of a stirrer or stirrers attached to a horizontal rotating shaft, arranged radially Within the tun, and which shaft, in addition to rotation about its own axis, has also a revolution about the vertical axis of the tun.

The object of our invention is to obtain a more thorough and uniform agitation of the mash than heretofore accomplished, to simplify the mechanism required, and to reduce the vertical dimension of said mechanism so that a steam coil may be placed in the mash above the revolving and rotating agitator, for the purpose of heating the mash.

Our invention consists in a single screwblade, revolving about or with a horizontal shaft which shaft itself revolves, also as the :radius of a circle, around the vertical axis of the tun, the direction ofthe revolution of the agitator being such that the edge of the screw-blade from the lowest point in its rotation moves in the same direction with the radial shaft in its revolution around the vertical axis of the tun, thus carrying the mash from the bottom ofthe tun forward and upward, and agitating the mash more eectually than if the screw-blade were revolved in the opposite direction; and our invention further consists in a steam-coil placed above the revolving agitator, for the purpose of heating the mash.

The following is a description of our invention, reference being had to the accompanying drawing, in which similar letters indicate corresponding parts in the different gures.

Figure l is a vertical section of a mash-tun provided with our invention. Fig. 2 is a plan view of the same.

A is a mash-tun. a is a revolving screwblade, keyed or otherwise made fast to the shaft c, which passes through the vertical shaft b, and is provided at the end opposite the screw-blade with the pinion d. The bearing of the revolving shaft farthest from the central shaft is in the rigid frame e made rigidly fast to the central shaft at f. g is the lower bearing of the upright revolving shaft b, and is made fast to the bottom of the tun, and to it is lnade rigidly fast the stationary gear h. t' is the upper bearing of the upright shaft, supported by any suitable frame or brace 7c. l is a steam-coil, placed over the revolving screw-blade, and made fast to the sides of the tun by suitable fastenings m.

When the shaft b is revolved the frame c and shaft c revolve with it, and as a radius of the same. The pinion d, engaging the stationary gear l1., rotates the shaft c and the screw-blade a. From the position of the pinion d the rotation of the screw-blade must, at the lowest point thereof, be forward in the direction in which its shaft is traveling in its revolution around the central shaft b, or in opposite direction from that which it would take if the pinion d were on the opposite side of the shaft b.

By making the agitator of a single screwblade we reduce the vertical space occupied by the agitator, so as to have room for the coil l, and the direction of rotation of the screw-blade due to the position of the pinion d, viz., on the side of b, opposite the screwblade, carries the mash up from the bottom of the tun, and thus agitates the same more effectually and uniformly than would be the case if the screw-blade were revolved in the opposite direction.

instead of a steam-coil, any other arrangement of steam-pipes or steam-radiators may be employed in the tun A.

We claiml. A revolving agitator, consisting of the single screw-blade a., rotating and revolving in the relative directions described, and for the purpose set forth.

2. The steam-coil or radiator l, placed in the mash-tun over the revolving agitator, substantially as described.
